NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 347,764, dated August24-, 1886.

Application filed July 9, 1886. Serial No.201,585. (No model.)

T on whom it may concern:

Be it known that I, JOHN BAKER, a citizen of the United States, residingat Hillside, in

. and claimed.

In order that my invention may be fully unders ood, I will proceed todescribe it with reference to the accompanying drawings, in which- VFigure 1 is a perspective view of my improved nut-lock. Fig. 2 is acentral longitudinal section through the bolt and lock. Fig. 3 shows theseveral parts of the device detached from each other.

In the said drawings, a designates the bolt, having a head, a, andthread a and b designates the nut, which screws upon the thread (H. Thebolt and nut may be of the usual or any preferred form, as my improvedlock is applicable to other than the precise form shown.

0 designates a sleeve, which may be either square, as shown, orpolyangular, and c designates the closed outer end of the same. Thisportion 0 is formed with a square or angular aperture, 0 as shown. Atthe front end of the sleeve 0 are formed two holes, 0 0 located onopposite sides of one of the angles of said sleeve, and designed toreceive either a rivet, (l, or a split key, 6.

In using this nut-lock, the threaded end a of the bolt is partiallyreduced, as at a, by pressure or filing, so as to correspond with theaperture 0 of the sleeve 0. A notch, b, is cut across one of the anglesof the nut b, or, in certain forms of nuts, a hole would be substitutedfor the notch. The nut having been screwed home, the sleeve C-is appliedto the bolt, so that its reduced portion a shall enter the aperture 0"of the sleeve, and so, also, that the holes 0" 0 shall lie in alignmentwith the hole or notch b of the nut. If the nut is to be permanentlylocked, the rivet d is inserted through the holes a and into the notchor hole I), and is clinched or upset against the sleeve, while if thenut is to be only temporarily locked the split key c is used andclinched in the usual manner.

The sleeve 0 is to be preferably of malleable iron, and will beconstructed in various sizes and different lengths in each size, to meetall requirements.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, with bolt a,having angular reduced portion a, and thenut I), having notch b, of the angular sleeve having angular aperture 0"in its end 0, and holes 0 and the locking pin extending through saidholes, substantially as set forth.

In testimony that I claim theforegoing as my own Ihave hereto affixed mysignature in presence of two witnesses.

JOHN BAKER.
